Food coloring spreads in water but not oil because the molecules that make up the coloring are soluble (able to be dissolved) in water. Water molecules are polar, which means they have an unequal distribution of charge on them. They are like little magnets, with a positive side and a negative side. Other particles with charge will be attracted to these little magnets, resulting in the material dissolving in water. The food coloring dissolves in water because its particles spread out amidst the water molecules due to this attraction.



Oil is a non-polar substance, which means that its particles have no charge. Other non-polar materials will dissolve in oil, but a polar substance will not. Hence the separation of oil and water when they are mixed together. Oil is also thicker then water

What happens when food coloring is added to oil and water?

  In a glass, usually the water is at the bottom and the oil on top, depends how you do it, but I did it once with the oil on top and the food colouring slowly went into t

In which water will the food coloring and oil spread faster in hot water or cold water?

Hot water, because it molecules are moving faster and thus the coloring will diffuse more quickly. In addition, if there is any kind of convection current (if there is a heat

Do all food colors spread out at the same rate in water?

they normally do. but when you have different type of colouring, then the results may differ   ex). you have solid food colouring and liquid colouring, then they spread at

Does food coloring spreads faster in milk or water?

Milk is mostly water but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. Fats and proteins are sensitive to changes in the surro

How does oil spread on water?

well oil is dense than water so it floats and the wind or larger body makes a wave so it pushes it across the water

Why does food coloring desolve faster in water than in cooking oil?

Oil is non-polar, the magnetic charge does not vary around the molecule. Water is polar, as the hydrogen atoms only have one election, which is taken up in their bonds with t
